Abstract

1,013,495. Making prestressed concrete pipes. N. DARRE-NILSEN. Dec. 6, 1961, No. 43757/61. Heading F2P. A core pipe 1 with end flanges 5 is first made, prestressed axially by reinforcement 2 and is wound under tension with reinforcement. 4. The axial prestress in the pipe 1 is then reduced to zero and a layer 3 of concrete cast between the flanges 5 and after hardening of the layer, the axial prestress in the core 1 is then permitted to operate again, so bringing the layer 3 under the same axial prestress. If the adhesion between the pipe 1 and layer 3 is adequate for the prestressing of the latter, the flanges 5 may be omitted.
